I need help setting up speakers

[fuzzyhair]

Yes, I posted this in the media center but nobody responded. I figured you guys would know what to do...

I just bought a KLH stereo system for my computer because it was really cheap and I need help setting it up. It has 5 speakers with 2 wires that snap into the back of each one. The only problem is that it only has 4 speaker inputs to my knowledge?!?! I am sure you guys will know what to do. I know I can just run two cables into one, but maybe I am just doing something wrong. It didn't come with directions or I would be all over them. Here's a picture of the speaker inputs:

Ususally for a 5.1 surrournd sound package you would use extra outputs on your sound card to supply the extra speakers. It seems like you would line out from your computer using a 1/8 to RCA(red/white) cable into the RCA inputs. The other outputs on your sound card should be yellow and black circles, one for center and one for the sub if my memory serves me right. If not there may be an output for the subwoofer on your control box. Make any sense? It should have the 1/8 to rca cable if you'd need it but then again some companies just expect you to have things
